Description
Waveguide variable attenuator 12WVA-20_Cu, operating from 60-90GHz,has a 0.3dB insertion loss, low VSWR 1.45:1, and up to 30dB nominal attenuation. 12WVA-20_Cu covers the WR12 full waveguide band and comes with two flanges FUGP740(UG-387/U). It can handle 0.5W continuously and 0.5KW peak power. The variable attenuator has a precision micrometer allowing for repeatable attenuation settings. The A-INFO's waveguide variable attenuator is manufactured with a high precision machining process to ensure high quality and ruggedness. The variable attenuator is an ideal component of equipment in waveguide systems where broadband attenuation is required. They are ideal for radar antenna systems, laboratory test set-ups, microwave radio, satellite communications, and other applications requiring low insertion loss, and low return loss. Different flange types may be available in stock, and please contact us to inquire further.
